SUBSTANCE: invention relates to methods of checking and forecasting condition of rail track. According to proposed method, running course of body of track-testing car is measured by means of inertia navigational system installed under pivot of test bogie, and running hunting angle of test bogie relative to body is measured by means of angular displacement transducer. Then, using axle box-rail transducers, distance from flanges of corresponding wheels of bogie to rail heads are measured. Basing on obtained information , running courses of rail lines are calculated as running course of body minus running hunting angle of test bogie relative to body minus running angle of parallel misalignment of flanges of wheelsets of test bogie and heads of rail lines. Then running values of horizontal irregularities of rail lines are found as product of bogie base by deflection of running course of rail lines from running averaged courses of rail lines on bogie base calculated from courses of rail lines. Running radii of curvature of rail lines are found by dividing bogie base by measured increment of course angles of rail lines on bogie base.
